The porcine circovirus type 1 (PCV1) has been identified within lymphoid tissues of experimental infected pigs and suggested to induce an immunosuppressive stage in pigs. The virus does not induce a cytophatic effect in the pig-derived cell line PK-15. Because PCV1 is prevalent in many pig cells and tissues, the risk of inducing a viral xenozoonosis by PCV1 was raised for the xenoimplantation of pig cells into human hosts. The present work evaluated if PCV1 is able to replicate in mice tissues after xenoimplantation of PCV1-infected pig cells. Active growing PK-15 cells harboring PCV1 with or without microencapsulation in sodium alginate were implanted into the peritoneal cavity of mice. After 1 month postimplantation in mice, peritoneal macrophages, spleen, and lymph nodes were harvested and analyzed with the polymerase chain reaction technique (PCR). No evidence of circovirus type 1 DNA was detected within the mice tissues.

More about this publication?
  • Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
